XD file missing

The Adobe XD file that I was working on has dissapeared. The program logged me out of my Adobe account and asked me to log back in. After I did this the file that I was working on for up to 100 hours was suddenly missing.

At first I was still able to see the file in the recently used files in the pop-up menu of Adobe XD on the taskbar, but after pressing it nothing happend... Now that I have restarted my computer it is not even visible in there. 

Please send help
